Software-defined Infrastructure:The convergence of Networking, Security and Cloud-based Software

CATO Networks

SD-WAN uses a software-based control plane to drive on-premise edge devices to dynamically allocate Wide Area Network (WAN) traffic between MPLS and Internet links. Lets start with the network. The core networking and network security layers of the IT infrastructure remained separate for more than 20 years.

WAN Optimization in the SD-WAN Era

CATO Networks

Born alongside the expensive MPLS data service, WAN optimization appliances allowed organizations to squeeze more bandwidth out of thin pipes through compression and deduplication, as well as prioritizing traffic of loss-sensitive applications such as remote desktops. Network security is built into the Cato Cloud.
